| Treg percentage of CD4 (%) | 1.95 ± 0.16 (1.30–2.40) | 2.07 ± 0.41 (1.41–2.39) | 0.824 |
| IgE (IU/mL) | 577.4 ± 131.4 (133.3–755.0) | 503.4 ± 111.2 (50.2–861.0) | 0.966 |
| FEV1 (L) | 1.38 ± 0.06 (1.22–1.48) | 1.39 ± 0.08 (1.20–1.67) | 1.000 |
| FEV1 predicted (%) | 89.9 ± 3.1 (80.0–98.6) | 92.3 ± 3.3 (83.0–101.5) | 0.564 |
| PEFR (L/min) | 306.4 ± 13.8 (265.5–349.0) | 321.1 ± 17.5 (280.5–352.5) | 0.447 |
| PEFR predicted (%) | 78.2 ± 4.0 (64.5–82.6) | 81.2 ± 3.0 (75.1–90.0) | 0.329 |
| FVC (L) | 1.60 ± 0.08 (1.32–1.78) | 1.63 ± 0.12 (1.26–2.12) | 0.952 |
| FVC predicted (%) | 87.7 ± 3.0 (77.5–96.8) | 92.0 ± 5.3 (77.0–101.0) | 0.627 |

| PAQLQ(S) | 139.3 ± 3.9 (130.5–156) | 150.0 ± 2.2 (141–158) | 0.065 |
Data shown are mean ± SE (interquartile range). Treg, regulatory T cells; IgE, immunoglobulin E; FEV1, forced expiratory volume in one second; predicted (%), the percentage of predicted value according to the age, sex, body weight, and height with reference from the Ministry of Health and Welfare in Taiwan; PEFR, peak expiratory flow rate; FVC, forced vital capacity; FeNO, fractional exhaled nitric oxide; C-ACT, childhood asthma control test; PAQLQ(S), the standardized pediatric asthma quality of life questionnaire. Reference range: leukocytes, 4000–10500/μL; eosinophils, 50–250/μL; IgE, <100 IU/mL; FeNO, a higher level correlates with airway inflammation: <20 ppb as low, 20–30 ppb as moderate, and >35 ppb as high concentration; C-ACT, a higher score reflects better controlled asthma: ≥20 as well controlled and ≤19 as not well controlled; PAQLQ(S), a higher score reflects better quality of life.
